High-frequency hot-sealing type catheter soft-hard head welding device

Abstract

The invention relates to a high-frequency hot-sealing type catheter soft-hard head welding device. The welding device is characterized by comprising a workbench, an insulating plate, a workpiece clamping and driving mechanism and a high-frequency hot-sealing type heating mechanism, wherein the workpiece clamping and driving mechanism comprises a linear guide rail, a clamping manipulator linear bearing, a linear bearing connecting plate, a clamping manipulator and a propulsion cylinder, and the high-frequency hot-sealing type heating mechanism comprises a negative electrode bracket, a negative electrode, a positive electrode driving cylinder, a high-frequency insulating pad and a positive electrode, and the high-frequency hot-sealing type catheter soft-hard head welding device also comprises a high-frequency output box, a baffle plate, a welding guide sleeve, an electrode output line and an electrode circuit line. The high-frequency hot-sealing type catheter soft-hard head welding device has the advantages of being used for producing soft-hard combined type medical interventional catheters, stomach tubes and intestinal tubes so as to facilitate the clinical intubation operation, solve the problem of difficulty in insertion of soft catheters, and shorten the operation time when medical personnel carry out interventional catheter propulsion, enema treatment or insertion of the stomach tubes on patients; and the welding device also can prevent the risk of injuring internal organs and vascular tissues in bodies of the patients by hard catheters so as to avoid bringing unnecessary pain to the patients.

Description

technical field [0001] The invention belongs to the field of medical catheter processing machinery, in particular to a high-frequency heat-sealing type catheter soft and hard head welding device. Background technique [0002] At present, medical interventional catheters have been used in the field of interventional treatment of intravascular diseases with the advancement of optical fiber technology, micro medical devices and computer technology. Insert the guide wire into the blood vessel, then insert the guide wire into the intervention catheter through the tapered port at the end of the intervention catheter, establish a track from the puncture point to the target blood vessel, advance the intervention catheter along the guide wire until the target blood vessel, and finally pull out the guide wire. The interventional catheter can be used for the next step of examination and treatment. However, during the advancement of the interventional catheter, due to the rigidity of t...

Problems solved by technology

The conventional enema treatment method directly uses an ordinary flexible plastic tube with a diameter of 8-15mm. The front end of the plastic tube is inserted into the patient's intestinal tract, and the back end is connected to the pipeline or instrument of the enema solution; It is easy to scratch the mucous membrane of the patient's intestines, causing pain to the patient

[0004] The gastric tube used clinically is made of soft material, and it is difficult to grasp the method when inserting it. It is easy to insert into the patient's trachea and cause the patient to cough
